The main advantages of small vacuum melting furnaces are:
- Helps remove adsorbed gases, significantly promoting shrinkage during the later stages of sintering.
- Removes impurities or oxides such as silicon, aluminum, magnesium, and calcium, effectively purifying materials.
- Improves wetting during liquid-phase sintering, aiding shrinkage and enhancing the alloy’s microstructure.
- Provides an ideal inert atmosphere; suitable for materials sensitive to decarburization or carburization when other inert or reducing gases are not suitable.
- Reduces contamination from harmful components in the atmosphere (water, oxygen, nitrogen, etc.). For example, achieving water content of -40°C in electrolytic hydrogen is difficult, but in vacuum sintering, a vacuum of several hundred Pa corresponds to the same water content.
- Fast melting speed; with an insulated jacket, temperatures can reach 2100°C. Optional programmable heating/cooling curves allow automatic operation according to your process requirements.
- Equipped with a tilting device to pour molten samples into prepared molds, creating the desired sample shape.
- Can melt under multiple atmospheres: air, protective gas, or high vacuum, allowing one furnace to achieve multiple functions and reduce costs.
- Optional secondary charging system allows adding elements during melting to prepare multi-component samples.
- The furnace body is made entirely of stainless steel with water cooling, keeping the exterior temperature below 35°C to ensure operator safety.
